On multiple occasions I have to manually turn on Low Power Mode when my battery is less than 10%. I remember my old phones turning it on automatically after a certain percentage. I currently have an iPhone Max 14 with the latest OS what gives? The setting always disables itself after a charge.
You can get this functionality back by creating an automation with Siri Shortcuts. Create a new personal automation > Battery Level > Drag the slider to your desired level > Select "Falls below X%". Choose "New Blank Automation" > search for Low Power Mode > Make sure it says "Turn Low Power Mode On" then click done!
